Existing roof fan hood structures are usually formed by welding or riveting steel plates, and some are made of glass fiber reinforced plastic materials, all of which are integrated structures. Completely remove the hood from the fan before removing the motor, impeller and other parts, which makes it extremely difficult to overhaul and maintain. Although there is a structure in the market that is a pair of open and closed roof fan hoods, it can be removed without complete removal. In the case of removing the wind cap, it is necessary to repair and maintain the internal parts of the fan, but its transmission device is complicated, the manufacturing cost is high, the opening and closing angle has certain limitations, and it is extremely inconvenient to transport and install the large integrated wind cap

Description
technical field [0001] The invention belongs to the field of fan technology, and in particular relates to a roof fan cap structure that can be quickly assembled and disassembled. Background technique [0002] Existing roof fan hood structures are usually formed by welding or riveting steel plates, and some are made of glass fiber reinforced plastic materials, all of which are all integrated structures. The motor, impeller and other components can only be removed after the hood is completely removed from the fan, which makes it extremely difficult to overhaul and maintain. Although there is a structure in the market that is a pair of open and closed roof fan hoods, it can be removed without complete removal. In the case of removing the wind cap, it is necessary to repair and maintain the internal parts of the fan, but the transmission device is complex, the manufacturing cost is high, the opening and closing angle has certain limitations, and it is extremely inconvenient to t...
